I've seen wildfire s ROMs with same cpu as pico being overclocked over 800 mhz. Explorer isn't much different I think..
[HTC Pico (Explorer)] jitin02:
Lets wait for yunnou, as in his first post he already told that he is trying and will post if something happens
[HTC Pico (Explorer)] sharap:
The good news. Phone is not heated up to 800 MHz?? Who can put the results of benchmarks on 800MHz?? (antutu benchmark)
[HTC Pico (Explorer)] jaggyjags:
Eager to try, but need to know how can I keep everything untouched and have an overclocked cpu.. Which of the 4 files do I need to flash and how?
[HTC Pico (Explorer)] vlc_marcos:
Is not possible to install this kernel with the recovery?
[HTC Pico (Explorer)] jaggyjags:
OK, so I tried it all, SetCPU has a max of 800mhz clock but it can't set it to the maximum. ondemand frequencies are 320 and 600mhz not 800! Can't modify max frequencies. Perflock can't be disabled in this custom kernel using the app option. Also tried system tuner and cannot move it to maximum frequency.. Any suggestions? I attach screenshot.. By the way, antutu benchmark stays around the same values.

[HTC Pico (Explorer)] jitin02:
check my tutorial. just focus on flashing my editted recovery.bat.
[HTC Pico (Explorer)] jaggyjags:
Done, tried the new over-boot.img for overclocking. Can't configure SetCPU :confused:. Check my post above
[HTC Pico (Explorer)] Yannou90:
Over-boot.img

Hi jitin02 and thanks you to have test this kernel :

-This kernel have some txeaks :

-ext support

-allow overcloked cpu : screen on 320 -> 800 MHz ; screen off 122 -> 480

BUT

Perflock is enable and don't allow user to change the cpu values , I've mad a new one with perflock disable and and the kernel allow 122->800MHz

I'm posting a video , and post the new kernel with modules

For your problem , what did you do exatcly , have you try the over-boot.img like this :

fastboot boot /full/path/to/over-boot.img

Or are you flash it like this :

fastboot flash boot /full/path/to/over-boot.img
[HTC Pico (Explorer)] jaggyjags:
I flashed it (fastboot flash boot)

OK, I'll try the new kernel and see
[HTC Pico (Explorer)] jaggyjags:
And what to do with the modules? I just moved the wifi bcm.. File.. It's that OK? Or do I have to move some more?
[HTC Pico (Explorer)] hoost_pt:
It is possible you to create a kernel zip file to install at cwr recovey?
[HTC Pico (Explorer)] markusssss:
was just what I wanted ..! I tried this configuration and I have to say it is perfect.
[HTC Pico (Explorer)] jaggyjags:
You overclocked it? How did you do it? I can't make it over 600. Just 320 and 600 mhz. Suppose it's because perflock look screenshot on the post above
[HTC Pico (Explorer)] jitin02:
Guyz wait flashable zip is on the way along with unlocked perflock

Just be paitient
[HTC Pico (Explorer)] vlc_marcos:
OK very nice, wait to try it. What is the perflick?
[HTC Pico (Explorer)] Yannou90:
Some big news

New kernel avalable :

Ext support and overclocked 122MHz -> 800MHz

Perflock disable , you can now manage the cpu !!

If you have a problem post here

I work on the stable release more light and fast , in some few days .
[HTC Pico (Explorer)] vlc_marcos:
What is the file to install on recovery.
[HTC Pico (Explorer)] jaggyjags:
Install the over-boot.Zip file

By the way, I installed it.. All perfect. Some improvement in benchmark. Not much dough... Here are screenshot before and after flashing.
[HTC Pico (Explorer)] vlc_marcos:
So kernel updated and now lets see the battery live, with the normal one i was getting 40 hours with wifi and sync with 1 email account and some calls and a lot of email, so now let se with this one :)
[HTC Pico (Explorer)] jaggyjags:
I am using cpu tunner and configured several profiles depending on the battery level and screen off. Underclocking to 122-320 when screen off and hopefully will expand battery life
[HTC Pico (Explorer)] calatemaze:
My phone crashed 2 times, which had never happened before. But other than that everything works perfectly so for. Thank you so much!
[HTC Pico (Explorer)] andresam:
Flashed your kernel and recovery 48 hours ago. All working great! Thank you!

Are you planning on releasing a custom ROM with A2SD+ and removing HTC Sense crap? :D I am using Link2SD but I noticed some of my internal storage is still consumed.
[HTC Pico (Explorer)] jaggyjags:
Just the app data. Do you know if the app2sd+ moves it all?
[HTC Pico (Explorer)] andresam:
I actually figure out what I was doing wrong. In link2SD settings, enable "Auto link" and in "Auto link settings" select all options. Leave "Install location" as Auto (I had it set to SD and link2sd was actually moving the apps to the FAT32 partition leaving dalvik-cache on internal memory instead of moving all to the ext3 partition).

I managed to link all existing User Apps I have to SD (Linked -> SD Card) leaving only Link2SD on Internal memory. Now have several Apps installed and 77MB free.
[HTC Pico (Explorer)] jaggyjags:
Check this,

European ROM is much lighter and i deleted rubbish apps to make it 144mb free memory just after installing the rom :)

Note: I deleted apps like Internet browser, gmail and mail because I use other apps from market for that purpose and have then linked. If you want then take them from the original rom and place it inside again.
[HTC Pico (Explorer)] Cosmoon:
Hi Yannou90,

I tried to get my explorer back up and running so far the only way through this http://xdaforums.com/showthread.php?t=1380086 thread.

But prob is that it's a english/chinees rom.

Then i found your thread and i tried to flash the damn thing in every possible way but still after installing and reboot the only screen i get is the very 1ste 'HTC Welcome screen".

attached pic is after installing your install-over-boot.zip i don't get any error. but when i reboot the phone stays on the HTC screen.

Any idea what i'm doing wrong?
[HTC Pico (Explorer)] jaggyjags:
same problem (not always) solved it by switching off and taking the battery away before booting again

I thought the problem came because I modified some system file... thanks
[HTC Pico (Explorer)] Cosmoon:
Oh didn't think about the obvious "did you try to switch it off and on again".

I was thinking it was maybe something about the rom. So searched google high and low for rom but none did the trick.

I've been fighting with this phone for a week now, even started to look into compiling kernel and building the damn thing from source.

i'll wipe and format everything and try your advice, thanks for the fast replay btw
[HTC Pico (Explorer)] Cosmoon:
jaggyjags tried it and got the same result.

Step 1

did a factory reset

wiped data, cache and Dalvik

even format data, cache, system etc

Step 2

Boot into fastboot

fastboot flash recovery over-recovery.img

go into recovery and push modules

Step 3

Power off

Take out battery

reboot

waiting waiting, ... still waiting but screen stays at "HTC"

Try 2

Same deal exept flash boot.img

Result = same

Try 3

simply go into recovery and install over-boot.zip from sdcard

result = same

Out off ideas now
[HTC Pico (Explorer)] jaggyjags:
off course, you need to flash a ROM!

check this,

flash the recovery and then install this three .zip files in order

(inside the .rar), you will have everything: modules, rooted and overclock

thank you i'll give it a go and let you know.

Allready tried different rom and got 2 results, or they didn't work or it was chinees.
[HTC Pico (Explorer)] deepaktom:
I've been using the overclocked one for almost 10 day now and its perfect. Yannou, are u skilled enough in porting roms? i'd been trying to port a wildfire s cm7 port into the explorer but that was a month ago and i failed miserably..
[HTC Pico (Explorer)] calatemaze:
Is there a way of having the ext2,3,4 support without the overclock?

It just keeps freezing, then I change the clock to 600mhz with setcpu (tried antutu cpu master also), but everytime I reboot it sets automaticaly to 800mhz.
[HTC Pico (Explorer)] andresam:
Thanks Yannou90!

I've been using your kernel (version 0.3) since released and I managed to use Android Kitchen to clean up / tweak the HTC stock image and enable apps2sd, so far so good.

Moving forward, I am wondering if you tried compiling ICS for the HTC Explorer using your kernel source. If yes, what was the outcome?
[HTC Pico (Explorer)] jaggyjags:
could you upload your work? cleaned image and so on.. :)
[HTC Pico (Explorer)] PeaceMaker_htc:
Keep up the good work guys!

can´t wait to try this on my explorer..

rooting was a sucess thanks to you! :D

Edit:

just updated the install-over-boot.zip in recovery mod...

checked the software info, the kernel is different, is that ok? is this all it takes? =)

Just installed CPU MASTER FREE, set the ondemand mode with min 122.88mhz and max 800mhz, is this ok for a normal use?

will the battery last as usual?

sorry for the questions, just entered Android paradise, lost half my life in the symbian hell :(
[HTC Pico (Explorer)] jitin02:
The default clocking which HTC managed to do (incase u choose normal in power menu in settings) is 480-600, and if overclocking to 800, of course sucks a lil more battery.
[HTC Pico (Explorer)] PeaceMaker_htc:
How does ext2 support works? Ive formated my sd card completly to ext2 and it's not recognized.. I am guessing it supports only ext as a second partition.. so normal fat32 partition and a second one ext2?
[HTC Pico (Explorer)] hoost_pt:
You should have two partitions, one fat32 and one EXT, preferably EXT4 with 4kb cluster because its quicker
[HTC Pico (Explorer)] PeaceMaker_htc:
Thanks, i´ve managed to have two partitions now, one first Fat32 and a Ext,

i´ve been reading about a "linux swap" space, is that really necessary?

also, using Link2sd moves apps but not it´s data, is there any other app that can move apps completely to 2nd partition? except from App 2 SD, from what i´ve been reading it can only move ALL the apps... i don´t want that...
[HTC Pico (Explorer)] jaggyjags:
I guess next step would be enabling cpu undervaltage in the kernel..
[HTC Pico (Explorer)] PeaceMaker_htc:
But it is.. i´ve installed Antutu CPu master checked that normal power state is ondemand from 122mhz to 800mhz..

I think it´s perfect for normal use..

But the overclocker in me thinks we can reach 1ghz :D:D
[HTC Pico (Explorer)] jaggyjags:
I mean undervolting to save battery, not underclocking, try searching Google :)

Is there any signs of excesive overclocking rather than overheating??. its cpu temperature is acting quite well at the moment with 800mhz so just starting to think we could take it a step further, but not an expert.
[HTC Pico (Explorer)] PeaceMaker_htc:
I know what undervolting is, I have read it wrong and tought u were talking about underclocking.. :rolleyes:

I think one of the signs of excessive overclocking would be crashing under heavy usage... at least on pc´s that´s it..

MANY THANKS!!! to @yannou90 for your kernel! :)
[HTC Pico (Explorer)] Yannou90:
Hi everybody

I don't have a lot of time to quicly response to your request

Excuse me

I have a website were I'm making some "how-to" and post all my work , It will be enable this week

I'll post it here too , sorry , be patient

For people who want more overclock : I make a kernel with cpu to 1080 MHz , but it cannot work , and there is no real use , with 800 MHz there are no lagg and no problem IF YOU DON'T MANAGE CPU

All is done by the kernel !

I've made a lot of package , here some features :

-Autobackup package : when you install the kernel for the first time a backup is made like this you have a nandroid backup with original boot , systeme and recovery .

Like this you could back from stock rom

Or test a recovery or kernel and if something went wrong you could back from it ( sorry for my english )

-Overclock kernel with perflock enable :

The cpu is overclock : 122 -> 800 but is manage by the kernel like this , screen on 122 -> 800 , screen off 122 -> 320

You cannot manage the cpu and perflock cannot be disable

-Overclock kernel with perflock disable :

The cpu : 122 -> 800 , you can manage the cpu but you should have some lagg or others problem

-Recovery with ext support : the chinesse recovery with ext support

-Recovery with ext support and overclock kernel :the chinesse recovery with ext support and overclock kernel , more fast for backup/install ...

-Last update : based on OTA_Pico_HTC_FRA_1.28.406.1-1.17.406.2_R_release_23103286679hi6t2f4r6gz.zip

(hboot 1.02 , original recovery , original boot , patch system)

-All modules : for geek , no real need but working

IF SOMEONE WANT MORE FEATURES TELL ME

For the probleme like bootloop or other it maybe occure because you use the chinesse boot.img or rom !

This pico work really strangely , there 's a lot of version but they are not compatible

In my case , If I use my stock rom and made a factory reset I have a boot loop

If I use the recovery to made a factory reset : boot loop

If I use fastboot made a factory reset : boot loop

If I flash system : boot loop

if I erase data : boot loop

For the people who want to back from stock rom and want to lock the pico's hboot : you lose boot and recovery your phone is semi-brick

You must have an update on your sdcard before , like PJ03IMG.zip , but this depend your cidnum ( mine HTC__203 )

All this recovery have the autobackup script , run it in update script or by adb shell to make a full backup ( with ext partition if it exist ) , you can use it in nandroid

Now the kernel is auto-undervolt , when the frequence scale , the power too

Thanks a lot
[HTC Pico (Explorer)] jaggyjags:
one question, how can a recovery have ext support and overclock kernel?

it wont backup ext partitions if it wasnt?

but what has that got to be with overclock? what things wont work if it wasnt overclock kernel support? or is it just faster to backup (more efficient..)

thanks

by the way, using the perflock dissabled kernel and havent notice any laggs, will check the other version to see if any difference..
[HTC Pico (Explorer)] sreerajpsin:

Can you add a Kernel Patch for 2 way call recording. It is used by CallRecorder and may be in many other HTC phone has it already.

Thank you.
[HTC Pico (Explorer)] PeaceMaker_htc:
I am using the kernel with perflock disabled, i guess..

works perfectly with Launcher PRO.

Htc sense not so great... a bit of lag..

but Launcher Pro doesn´t load my contacts profile photo from facebook :mad:
[HTC Pico (Explorer)] jaggyjags:
when wiping system memory it always formats the ext partition to ex3, could you make it stay the same as before?
[HTC Pico (Explorer)] calatemaze:
I've tried your kernel without the setcpu and its still unstable.

Still I think it's weird that it's not happening to anybody else.

Since you asked I'd prefer to have

The cpu : 122 -> 600mhz

and

Kernel with ext2,3,4 support

Or just make the 0.1 version of kernel available again.

Thank you.;)

News , revert back to stock rom with latest ota update !

-clean-update.zip :

Copy it on your sdcard , reboot into recovery , apply update from sdcard !

That's all , you have a stock rom with last update , you lose boot.img and recovery.img , but you can flash it , new hboot but always unlocked !!

Revert back to stock rom with latest update :

-new boot.img with wifi modules

-new recovery

-new radio.img

-new hboot.img , always unlocked

-patch system update

Find it here
[HTC Pico (Explorer)] jaggyjags:
Thankyou!!

can you clarify it a bit?

so you flash it and have same but with s-off?

with not boot so have to flash boot.img after?

do we have to rename to "update.zip"?
[HTC Pico (Explorer)] Yannou90:
This is the official update OTA_Pico_HTC_FRA_1.28.406.1-1.17.406.2_R_release

If you install it you revert back to stock rom : original boot recovery, you lose custom recovery and boot ; new hboot and radio , but hboot stay unlock,you can flash your phone

You can use it if you have some problem with your phone

This update don't touch userdata partition , you lose nothing .

After this update if you want custom recovery or/and boot you must flash it again
[HTC Pico (Explorer)] jaggyjags:
Thanks, hope to see your perflocked kernel soon :)

So can you explain me something. This update is to put the phone stock again? I because iam suing a custom ROM jaggy, a 1.17 radio version. So should I update it with this update? Sorry for the mess.
[HTC Pico (Explorer)] Yannou90:
This is an official update , I just remove some command in the update.script because I cannot install it : I use a custom boot and recovery !!

Well , I modify the update.script and apply it : It work !!

Made some test : it patch some official apk and files , and upgrade boot + recovery + hboot +radio

You don't lose data , you have a new official rom : stock boot , recovery + new hboot +new radio

You lose custom boot , recovery and ext partition .

Your ext partition is or your sdcard but the stock kernel have no ext support

If you have unlocked your pico it's great you don't lose it and you can flash a custom boot or recovery

WARNIG : IF YOU USE AN EXT PARTITION YOU LOSE YOUR DATA BECAUSE YOU LOSE CUSTOM BOOT

MAKE A FULL BACKUP WITH NANDROID OR OTHER TITANIUM ...

IF YOU USE THIS UPDATE :

1) full backup with titanium or other and recovery mode -> nandroid backup

2) apply update

3) reboot the phone : it will reboot in 3 time

4) reboot in fastboot mode

5) Now we apply a fake flash to boot with over-recovery.img :

fastboot boot /full/path/to/over-recovery.img

The phone reboot in recovery

6) nandroid backup

Like this you have a stock rom with update

7) That's all

You can now flash boot system recovery , install rom , make what you want you can back to official rom (not system !!)

Find here the official update.script
[HTC Pico (Explorer)] jaggyjags:
is it possible to create a stock rom with the 1.28 update?
[HTC Pico (Explorer)] Yannou90:
No there is no system.img

It is possible but you must mod the update.script , add your system , patch him , apply update but it's a non-sense it's not a real rom

I have lock my pico and apply ruu eur to have original rom

Re-unlock it

Apply update

Fake boot recovery with fastboot

fastboot boot /full/path/to/over-recovery.img

Made a nandroid backup

Now I have a stock rom with update

How to install zImage.7z file in post 4?
[HTC Pico (Explorer)] Yannou90:
zimage is kernel

If you want to use it you must have all modules , like wifi modules

When you have all modules and kernel , do what you want !!

zImage is an image that is charged in boot process ( boot , recovery )

You cannot " install " it

You can use it !

You can use it in boot or recovery

To use it you must have it own modules like wifi

If you want to custom it you must have :

- Original sources ( by htc for pico )

- Cross compiler installed and enable

- Know what you do

- Made custom boot , custom recovery , or compile it

- Compile kernel and modules

- Make kernel charge or not , to boot process , the modules you need

To be clear :

Or you know what you do and you must have official sources and cross-compile it ( arm) , likes this you know what you do and have all modules , or you can custom boot or recovery : extracted all files , replace zImage , re-create image boot or recovery !

good luck
[HTC Pico (Explorer)] jaggyjags:
how is your web going?

hoping to see your perflocked kernel soon

will it be too bothering if you uploaded here for the time being before you build your site?

cheers
[HTC Pico (Explorer)] Yannou90:
There is no real diff with stable and beta because I have no bug with beta .

I says "Undervolt" but I don't really undervolt :

In kernel I can active autovolt , but it adjust the voltage with cpu and other ...There is no real need , we want our smartphone verry strong when we want !!

If I disable perflock , the Pico is undervolt becauve it scale 122->800 , in real , with perflock enable , minimum scale is 320 , if I disable perfolck and allow 122MHz to minimum and 800MHz to maximum , with screen on or off , the cpu is always to 122 , the power down that's all !!

It go up to 800 MHz if I use it , and please don't use set-cpu or other , they can occure some bugs with kernel : it work with some devices , fine :rolleyes:

But with other it made some bugs ! :eek:

Use no-perflock boot.img alone , please , and tell me if there si some bugs .

Thanks .

Now I'm working on my website , it's for my familly , I love them , sorry !! ;)

On it , some parts is for android , an other for bash scripting , and the most for familly !

I'll post all here ( no-familly :) , no problem ! ) , all my pico's work , I have really some troubles with english language , sorry :mad:

I 've made a how-to for unlock without flash , because there is no need to flash recovery or boot (chinesse version) , or you want to have some trouble with wifi !

We can have an original rom with official update AND custom boot ( and wifi modules ) and recovery , it is what I do :cool: , i'll post it too !!

Nobody want the pico : it is so small , no money :D !

I love it , and you too !!
